METHOD AND SERVING BASE STATION FOR DETERMINING HANDOVER TYPE, AND METHOD FOR HANDOVER BETWEEN BASE STATIONS IN WIRELESS MOBILE COMMUNICATION SYSTEM USING CARRIER AGGREGATION

摘要

Provided are a method and a base station for determining a handover type, and a method for handover between base stations in a wireless communication system using carrier aggregation. A serving base station may collect measurement information required to determine an optimal frequency band set from a neighboring base station and a user equipment. The serving base station may determine an optimal frequency band set for downlink handover and uplink hand over, and determine a type of the downlink handover and the uplink handover by performing data processing of the collected measurement information.
